This document discusses the importance of mathematics libraries in schools. It recommends that schools have both a general school library with a dedicated mathematics section, as well as a mathematics department library. The general school library should contain reference books, textbooks from different countries, books on teaching techniques, and books for recreational reading related to mathematics. The mathematics department library should focus on reference books for daily use by students and teachers, current popular books, and books on mathematical developments and applications. Regular library periods and assignments are suggested to encourage library use.
